Is it safe to remove script from DOM?

Question

JavaScript

How do web browsers react to this action? Do all the objects and functions declared in this script remain alive, or are they killed by the garbage collector?

Answer 1

Browsers respond normally. You can delete scripts, but there is no benefit in this. All objects will be created and they will hang in memory until someone or something refers to them.

Answer 2

What for? And why not just check?

Answer 3

I don't understand why this is needed?
